a man tosses a coin. if it turns head the man walks 10 m North. if it turns tail 10 m South. Find the probability that after tossing the coin 8 times he is 20m S of the starting position.
--------
Binomial Problem with n = 8 and p(h) = p(t) = 1/2
-----------------------
Required pattern:: 5 tails and 3 heads.
P(x = 5) = 8C5*(1/2)^8 = 56/256
